摘要
通过野外调查和资料分析,并对外来植物的原产地、分布特点、引入途径等进行分析。结果表明,①台州目前有92种外来植物,属于39科,81属,其中有栽培种41种、归化种11种、外来入侵种40种;②台州市外来植物来自美洲52种,来自欧洲12种,分别占总数的56.52%和13.04%;③台州市外来植物在温岭分布最多(84种),其次是椒江(81种);④属的区系地理成分划分为13种分布区类型,热带分布成分(61.73%)比温带分布成分(38.27%)强,表现出台州外来植物的过渡性和复杂性。
Based on the field investigation and analysis of related literatures, the flora composition, origin area, distribution area and import pathway of alien plants in Taizhou are discussed. The results show that： （1） there are 92 species belonging to39 families, 81genus, including 41 cultivated species, 11 naturalized species, 40 alien invasive species; （2） there are 52 species （56.52 %） from America and 12 species （13.04 %） from Europe; （3） 84 species are distributed over Wenling areas and 81species distributed over Jiaojiang areas. （4） the 81 genera distributed in Taizhou can be divided into 13 areal types, which belongs to the tropical distribution pattern plant （61.73 %） and temperate one （38.27 %）. Alien plants in Taizhou are characterized by flora environment transition nature and complexity.
